    Re: Bowditch long term almanac
    From: Geoffrey Kolbe

    There does seem to be a considerable difference between the 1956
    epoch LTA and the 1972 epoch LTA as given in Bowditch, so it would
    seem that the corrections were not transplanted wholesale as I suggested.
    
    That still leaves the problem as to why the given 1972 epoch
    quadrennial corrections are so poor. I tried to determine the period
    of validity - or at least the period over which the corrections would
    have been calculated, but I could not. It was at that point that I
    gave up and created my own.

    I am not sure what you are saying here. Perhaps you could restate it?
    
    Too, I am afraid the accents in your name mean that your name is
    reproduced as gibberish on my computer. I would be grateful for an
    un-accented version of your name so I can address you personally.
